We apply a pair-wise approach to test the law of one price for deposit (lending) rates in Colombia. We find that when banks are of different size deposit rates adjust quickly, suggesting a competitive environment. By contrast, lending rates adjust rapidly when banks are of similar size, supporting market segmentation.
